I consider Bill a friend as well as a teacher. His grace and poise while going through this made me re-evaluate my own considerations about my focal dystonia and has inspired me in a way that I would never have expected.
For any of you who have never seen him, do yourself a favor and check out his otherworldly playing:
Bill, I'm saddened, relieved, & inspired by your post. I had a brain stem stroke last July, & like you, it hit me hard, so, to a degree, I understand your challenge & journey. For a simple player like me, it was bad enough, but for a player of your facility, it's significantly more devastating.
FWIW, you have exactly the right mindset - back on the horse - force change. My biggest issue was perception as much as function, and I still have some hangovers from it, but I was lucky enough to recover well, and I'm sure you will do likewise.
